CMAP_ITER_INIT(3) Corosync Cluster Engine Programmer's ManualCMAP_ITER_INIT(3)NAMEcmap_iter_init - Initialize iterator for keys stored in CMAP
cs_error_t cmap_iter_init (cmap_handle_t handle, const char *prefix,
The cmap_iter_init function is used to initialize iteration of all keys
with given prefix. The handle argument is connection to CMAP database
obtained by calling cmap_initialize(3) function. prefix is string, and
every returned key must have name with given prefix. This variable can
also be NULL (or empty string) and then all keys are iterated.
cmap_iter_init is used only for initialize context for future
cmap_iter_next(3) calls and handle needed for that function is returned
in cmap_iter_handle variable. When you have finished iteration over
objects, call cmap_iter_finalize(3) function to free up memory associ‐
ated with iteration.
This call returns the CS_OK value if successful. If there are no items
with given prefixes, CS_ERR_NO_SECTIONS is returned.
